Charger Disconnects/Reconnects When Minimizing/Maximizing Games (ROG Strix G16 G614JZ, 330W PSU)

Hello. I'm experiencing a critical issue with my ROG Strix G16 (Model G614JZ, i7-13650HX + RTX 4080). Whenever I minimize/maximize games or use Alt+Tab or in any other case of a sudden increase or decrease in the wattage of the graphics card

  1. The charging LED turns off for 2-3 seconds (white light disappears).

  2. Windows shows "Connected, not charging" → then switches to "Charging".

  3. Simultaneous FPS drops and micro-stutters occur.

Reproduction Steps:

  • Games: Any demanding titles (Cyberpunk 2077, Alan Wake 2, Horizon Zero Dawn).

  • PSU: Original 330W adapter.

  • Software:

    • BIOS 331,

    • NVIDIA Driver 576.88.

  • CPU/GPU Temps: CPU - 80-90, GPU - 85-87 (hotspot - 105).

Troubleshooting Performed:

  1. EC reset (held power button 40 sec without PSU).

  2. Disabled all optimizations in GeForce Experience + Windows.

  3. Tested with different 330W PSU.

  4. Replaced power jack.

P.S. This severely impacts gaming - causes micro-freezes and ruins online matches. Generic solutions (OS/driver reinstall) have been attempted without success.
